This is my opinion only. Personally I am single, and if I was in a relationship I would never hobby. I have always been faithful in my relationships. I have learned that "Love" is an important thing in life for one to get by. Money comes and goes. Age and Time don't stop for anybody. So I think it is better to take a step now rather than regret it later thinking about "What could have been?".
One day it will end for everybody, how would you like your story to end is in your hands.
My 2 cents.
